I am trying yo run inferences with detect.py from ultralytics yolov5 (https://github.com/ultralytics/yolov5).
I created a Python environment under Windows 10, with python 3.9 and installed the requirements.txt.
I checked opencv installation and have FFMPEG set to YES.
I can run inferences on my webcam using --source 0.
However, I cannot run inferences on a rtsp stream, which works on VLC for example (no problem with the rtsp link).
The error is from utils/datasets.py, line 309 : opencv cannot open the VideoCapture.
I tried adding the backend like this : cap = cv2.VideoCapture(rtst_path, cv2.CAP_FFMPEG).
I also tried to add this line before opening the cap : os.environ["OPENCV_FFMPEG_CAPTURE_OPTIONS"] = "rtsp_transport;udp"
None of this works. I guess it comes from my environment. Any help ?
